Hi all, I have some good news for you. I was able to fix the issue with the P.A. Semi Ethernet. It was a problem with the new DMA handling. The patch ' [RFC/PATCH,v2] powerpc/iommu: Support "hybrid" iommu/direct DMA ops for coherent_mask < dma_mask

Hi Michael, Thanks a lot for your answer. We tested some vanilla mainline 4.3 kernels on an Electra reference board. Additionally we tested some patched 4.3 kernels on our Nemo boards. It would be really fantastic, if you could fix the problem. Cheers, Christian On 02 December 2015 at
